IMPROVEMENT IN ATTAGHING vWHEELSTO AXLES.

TO ALL WHOM IT MAY GONCIIRN;

Beit known that I, GEORGE W. SAWIN,-of Nashua, in the county ofHillsboro, and State o f NewHampshire, have invented certain new anduseful Improvements in the Metho of Attaching Wheels to Axles; and I dohereby declare that the following is a full and exact descriptionthereof, reference being had to the accompanying drawings, and totheletters of reference marked thereon. v

The nature of my invention consists in attaching to the hub twospring-latches, arranged in` such a manner that when the hub isplacedupn vthe a'xle the latches shall catch over the edgeof a ring,whichis permanently fixed upon the axle; 4 also in arrangement forlubricating. Y

To enable others skilled -in the art tom'ake and use my invention, Iwill proceed to describe its construction and operation.

In the drawings-m Figure 1 isa perspective view, showing the hub andaAportion of the'axle; also the ends of the spring; latches and thering, v

Figure 2 is a sectional view ofthe same.

Figures 3 and 4 represent in front and side elevation a pair ofpeculiarly-formed tongs, which are used for the purpose of springing thelatches back when it is desirable to remove the hub.

A'represcntsa hub of ordinary construction, having inserted within andpermanently attached to it the spring-latches E E; the said latcheshaving hooks L L at one end, and being secured to the hubs hy nuts F atthe opposite ends. H is a ring, attached permanently to the axle-B,overA the edge of which tho hooks L L catch, as showh in lfigs. 1 and 2.i I

The end of the axle within the huh is provided with channels D G C, fig.2, in which thcsurplus lubricatingmatter may remain.

M represents a cap, which may-he packed with cotton-waste, or somesimilar material, K, fig. 2, whichl may .As the endsof the latches E Eform an incline, as shownat L, the hub may be slipped on-tlle end of theaxle, the latches being'thrown back by simply coming iu contact with thering H, so as to pass over'rit and then snapinto place.

To facilitato removing the hub from the axle, I use a peculiarly-formedtongs, shown in figs. 3 anrdf4, each leg oi the tongs `being providedwith ashort prism, P P.

To remove the hub, I so place the tongs upon the axle that one of theprisms P P shall be in contact ,-with.

L, and the other with L. Now, by holding them flrmlyngainst the ring H,and at the sametimeturn'bng the' wheel, the hooks L IKwill be pushedoutward until'they are free from the ring H, when tho hub may be removedfrom the axle. t

Having thus described my invention, 4I will now proceed to set forth myclaims.l

What I claim my invention, and desire to secure by Letters Patent', is

The combination of the latches E E with the hub A and ring Il, rnadcsubstantially as describ ed and for the purpose set forth.
